Leveraging Similarities

We tend to think every technology and every product is roughly unique—so we tend to stay up late at night looking at packet captures and learning how to configure each product individually, and chasing new ones as if they are the brightest new idea (or, in marketing terms, the best thing since sliced bread). Reality check: they aren’t. This applies across life, of course, but especially to technology. From a recent article—

Whenever I start learning a new programming language, I focus on defining variables, writing a statement, and evaluating expressions. Once I have a general understanding of those concepts, I can usually figure out the rest on my own. Most programming languages have some similarities, so once you know one programming language, learning the next one is a matter of figuring out the unique details and recognizing the differences.

RFC1925 rule 11 states—

Every old idea will be proposed again with a different name and a different presentation, regardless of whether it works.

Rule 11 isn’t just a funny saying—rule 11 is your friend. If want to learn new things quickly, learn rule 11 first. A basic understanding of the theory of networking will carry across all products, all Continue reading

Juniper Master Class: Disaggregation Pros and Cons

On the 28th—in two days—I’m doing a master class over at Juniper on DC fabric disaggregation. I’ll spend some time defining the concept (there are two different ideas we use the word disaggregation to describe), and then consider some of the positive and negative aspects of disaggregation. This is a one hour session, and it’s free. Register here.

Commands to find Linux-package updates

Did you know that you can ask your Linux system to tell you what upgrades are available for the packages installed on it? You might be surprised by how many you’ll see, especially if you’re using the current release and don’t have your system set up for frequent or automatic updates.Updates play an important role in keeping your Linux systems secure and performing well. Since most packages are updated as fixes or improvements to the code become available, it’s hard to predict how many will show up on any particular day. (Note: Updates should be done when your system is not performing other important tasks.)Finding installed packages on Fedora Linux systems Fedora and related systems To check what updates are currently available for your Fedora or related system, use a command like this:To read this article in full, please click here

Understanding Where the Internet Isn’t Good Enough Yet

Understanding Where the Internet Isn’t Good Enough Yet
Understanding Where the Internet Isn’t Good Enough Yet

Since March 2020, the Internet has been the trusty sidekick that’s helped us through the pandemic. Or so it seems to those of us lucky enough to have fast, reliable (and often cheap) Internet access.

With a good connection you could keep working (if you were fortunate enough to have a job that could be done online), go to school or university, enjoy online entertainment like streaming movies and TV, games, keep up with the latest news, find out vital healthcare information, schedule a vaccination and stay in contact with loved ones and friends with whom you’d normally be spending time in person.

Without a good connection though, all those things were hard or impossible.

Sadly, access to the Internet is not uniformly distributed. Some have cheap, fast, low latency, reliable connections, others have some combination of expensive, slow, high latency and unreliable connections, still others have no connection at all. Close to 60% of the world have Internet access leaving a huge 40% without it at all.

This inequality of access to the Internet has real-world consequences. Without good access it is so much harder to communicate, to get vital information, to work and to study. Inequality of access Continue reading

Why I joined Cloudflare — and why I’m excited about Project Pangea

Why I joined Cloudflare — and why I’m excited about Project Pangea
Why I joined Cloudflare — and why I’m excited about Project Pangea

If you are well-prepared to take up the challenge, you will get to experience a moment where you are stepping forward to help build a better world. Personally, I felt exactly that when about a month ago, after a long and (COVID) complicated visa process, I joined Cloudflare as a Systems Engineer in Austin, Texas.

In the early 2000s, I experienced while travelling throughout the Benin Republic (my home country) and West Africa more generally, how challenging accessing the Internet was. I recall that, as students, we were often connecting to the web from cybercafés through limited bandwidth purchased at high cost. It was a luxury to have a broadband connection at home. When access was free (say, from high school premises or at university) we still had bandwidth constraints, and often we could not connect for long. The Internet can efficiently help tackle issues encountered (in areas like education, health, communications, ...) by populations in similar regions, but the lack of easy and affordable access, made it difficult to leverage. It is in such a context that I chose to pursue my studies in telecoms, with the hope of being able to somehow give back to the community by Continue reading

Announcing Project Pangea: Helping Underserved Communities Expand Access to the Internet For Free

Announcing Project Pangea: Helping Underserved Communities Expand Access to the Internet For Free

Half of the world’s population has no access to the Internet, with many more limited to poor, expensive, and unreliable connectivity. This problem persists despite large levels of public investment, private infrastructure, and effort by local organizers.

Today, Cloudflare is excited to announce Project Pangea: a piece of the puzzle to help solve this problem. We’re launching a program that provides secure, performant, reliable access to the Internet for community networks that support underserved communities, and we’re doing it for free1 because we want to help build an Internet for everyone.

What is Cloudflare doing to help?

Project Pangea is Cloudflare’s project to help bring underserved communities secure connectivity to the Internet through Cloudflare’s global and interconnected network.

Cloudflare is offering our suite of network services — Cloudflare Network Interconnect, Magic Transit, and Magic Firewall — for free to nonprofit community networks, local networks, or other networks primarily focused on providing Internet access to local underserved or developing areas. This service would dramatically reduce the cost for communities to connect to the Internet, with industry leading security and performance functions built-in:

  • Cloudflare Network Interconnect provides access to Cloudflare’s edge in 200+ cities across the globe through Continue reading

Introducing Flarability, Cloudflare’s Accessibility Employee Resource Group

Introducing Flarability, Cloudflare’s Accessibility Employee Resource Group
Introducing Flarability, Cloudflare’s Accessibility Employee Resource Group

Hello, folks! I’m pleased to introduce myself and Cloudflare’s newest Employee Resource Group (ERG), Flarability, to the world. The 31st anniversary of the signing of the Americans with Disabilities Act (ADA), which happens to fall during Cloudflare’s Impact Week, is an ideal time to raise the subject of accessibility at Cloudflare and around the world.

There are multiple accessibility-related projects and programs at Cloudflare, including office space accessibility and website and product accessibility programs, some of which we will highlight in the stories below. I wanted to share my accessibility story and the story of the birth  and growth of our accessibility community with you.

About Flarability

Flarability began with a conversation between a couple of colleagues, almost two years ago. Some of us had noticed some things about the workspace that weren't as inclusive of people with disabilities as they could have been. For example, the open floor plan in our San Francisco office, as well as the positioning of our interview rooms, made it difficult for some to concentrate in the space. To kick off a community discussion, we formed a chat room, spread the word about our existence, and started hosting some meetings for Continue reading

Outage Reporting

With so many enterprises all over the Internet forced to make a choice between just a handful of viable content distribution platforms for their content and services then nobody should be surprised when a single platform's outage has massive service impact. But that's not what's prompted me to write this note. It's Akamai's report of the incident that I found unusual.

Comparing Open Source BGP Stacks

Open source BGP stacks are very important, but I don’t think they get the love they deserve. There’s lots going on in open source BGP stacks and I can’t keep up. So I thought I’d like to quantitatively compare them. This is one, often tiny, aspect of evaluating a BGP...

Welcome to Cloudflare Impact Week

Welcome to Cloudflare Impact Week
Welcome to Cloudflare Impact Week

If I'm completely honest, Cloudflare didn't start out as a mission-driven company. When Lee, Michelle, and I first started thinking about starting a company in 2009 we saw an opportunity as the world was shifting from on-premise hardware and software to services in the cloud. It seemed inevitable to us that the same shift would come to security, performance, and reliability services. And, getting ahead of that trend, we could build a great business.

Welcome to Cloudflare Impact Week
Matthew Prince, Michelle Zatlyn, and Lee Holloway, Cloudflare’s cofounders, in 2009.

One problem we had was that we knew in order to have a great business we needed to win large organizations with big IT budgets as customers. And, in order to do that, we needed to have the data to build a service that would keep them safe. But we only could get data on security threats once we had customers. So we had a chicken and egg problem.

Our solution was to provide a basic version of Cloudflare's services for free. We reasoned that individual developers and small businesses would sign up for the free service. We'd learn a lot about security threats and performance and reliability opportunities based on their traffic data. And, Continue reading
